The Equal Employment Opportunity Commission has asked an appeals court to set aside a record-setting $4.6 million attorney fee award imposed on the agency following a botched sexual harassment lawsuit against trucking company CRST Van Expedited Inc.

In a 127-page brief, filed on Thursday at the U.S. Court of Appeals for the Eight Circuit, EEOC argued that U.S. District Judge Linda Reade in Iowa City, Iowa, erred in her Aug. 1 ruling that CRST was the prevailing party in the case and ordering the agency to reimburse the company $4.1 million in attorney fees and $500,000 in costs—believed to be the largest such award in EEOC’s history.
